%X Nanometer particles composed of manganese oxides (Nano-MnO(x)), which prepared by rheological phase reaction method, show superior low-temperature SCR activity for NO with NH3 in the presence of excess O2. In experiments, the NO conversion is 98.25% at 80 degrees C, and nearly 100% NO could be converted in 100 - 150 degrees C. Due to the reason of competing adsorption, H2O has a slight impact on the activity and the deactivation of SO2 is reversible. The experiments implied that the superior low-temperature catalytic activity of Nano-MnO(x) was mainly due to its high BET specific areas and poor crystallinity.
